I guess the FS2 is designed more for those low and mid grip tracks, and super smooth clay like they have in Japan and the states, where a little more rotation is required. The friont end just does not have enough traction to 'pull' the car around the corners like we have in this country from high grip carpet, AND pins. The minispikes will slow down reaction and response of the front end on carpet, so should help your situation Rog. Or just stick with the FS!
